ECC Registered DDR3L Kit for Cisco UCS Blades

This OWC kit supplies 16 GB of DDR3L 1600 ECC Registered memory as two 8 GB RDIMMs. The modules run at 1.35 V with CL11 latency and a 2Rx4 organisation. They are qualified for Cisco UCS B260 M4 E7 v2 and v3 plus B460 M4 E7 v2 and v3 blade servers.

For servers needing registered ECC — not

The RDIMMs are designed for workstation and server platforms that require registered ECC memory. They will not work in standard desktop computers and must not be mixed with unbuffered or load-reduced DIMMs. Buyers without a compatible Cisco UCS blade should look elsewhere.

240-pin DDR3L 1600 Registered form factor decides

Each stick uses the 240-pin DDR3L RDIMM form factor at 1600 MT/s. The registered buffer and ECC logic are mandatory for the target Cisco UCS B260 M4 and B460 M4 systems. If the server calls for a different pin count, voltage or buffer type, this kit will not install.

Questions about this item

Will the registered ECC RDIMM modules need any firmware updates or periodic replacement?

No firmware updates are required; the modules are solid-state with no moving parts and are designed to last the life of the Cisco UCS B260 M4 or B460 M4 server.

What is the first limit reached when the kit runs at DDR3L 1600 continuously?

The CL11 CAS latency at 1600 MHz sets the timing boundary; sustained throughput cannot exceed the PC3L-12800 data rate.

How much heat and power does the 2Rx4 1.35 V kit produce under all-day load?

Each 8 GB module operates at 1.35 V without a heat spreader; total power draw stays within standard DDR3L limits for registered DIMMs.
